Sealants are materials used to block the penetration of liquids, gases, dust, or other contaminants from one area to another by creating an adhesive barrier. Many sealants function as both a barrier and an adhesive, giving strength to sealed substrates. Sealant applications can vary greatly and the sealant products available exhibit a wide range of properties, including their base chemistry and cure mechanisms, adhesive strength, elongation, resistance to water, other liquids, and environmental stresses, and preferred application method. Ellsworth Adhesives supplies Anaerobic, Silicone, UV Cure, Polyurethane, Silyl Modified Polymer, and Polysulfide sealants, among others.
